“…It is shown that the effect of this technology is higher in NEDC rather than in WLTP-H, since it is more effective in the lower speed/load area of the engine operating map. The CO 2 effect of lean-burn technology is well within the suggested range proposed by other works, which is from 2% to 6% [65,107]. The application of lean burn technology results in a reduction of CO 2 emissions from 3.8% to 8.3% with an average of 5.5% in NEDC and from 2.2% to 4.5% with an average 3.3% in WLTP-H.…”

“…Compared with conventional injection into the inlet manifold, this process is considerably more precise and is not dependent on the opening times of the valves. However, care has to be taken concerning NO x emissions, which may increase in such combustion systems [65]. In this study, a modified fuel consumption map was used, which have been produced by applying a dimensionless average delta map on the original engine fuel consumption map.…”

“…Homogeneous charge compression ignition (HCCI) is a part-load combustion method, which is characterized by lean low-temperature combustion (LTC) with temperatures below the oxides of nitrogen (NO x ) formation temperature of 2000 K. As a result, HCCI has the potential to significantly reduce NO x emissions, while maintaining a high fuel efficiency, comparable with current stratified lean-burn combustion, with NO x emissions reduced by up to 99%. 13 Therefore, expensive exhaust aftertreatment systems can be reduced or simplified. 4 Efficiency also improves when using HCCI combustion due to the rapid global and spatial combustion in combination with reduced wall heat losses from the LTC.…”

“…HCCI has the potential to significantly reduce NO x emissions by as much as 99% when compared with current stratified lean-burn gasoline combustion. 1–3 Therefore, expensive exhaust after-treatment systems can be reduced or simplified. 46 HCCI utilizes rapid multi-site combustion, and this in combination with reduced wall heat losses from LTC leads to thermodynamic and fuel efficiency benefits of up to 30% over current gasoline engines.…”
